Application filed February 17, 1920. Serial No. 359,244.

To all whom it may concern:

Be it lmown that I, ORED OLssoN, a citizen of the United States, and aresident of ()rd, 1

A further object 1s to provide an improved construction and mounting forthe governor;

A further object is to provide improved means for preventing thewindmill from being forced out of operation by a sudden blast of air. s

A further object is to provide'a windmill which embodies in itsconstruction various novel details which coeperate in the provision of awind wheel which will most efliciently perform the functions for whichit,

is intended.

With these and other objects in view the invention consists in certainnovel features of construction, and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings- Figure 1 is a view in side elevation withcertain of the blades or vanes and operating parts removed for purposesof clearness;

Fig. 2 is a view in elevation at right angles to Fig. 1;

Fig. 3 is an enlarged view in longitudinal section through one of. theblades or vanes, the section being taken on the line 33 of Fig. 1; 7

Figs. 4, 5 and6 are transverse sectional views of a blade or vane, saidsections being indicated by the lines 4-4, 55, and 6-6 respectively ofFig. 1; v

Fig. 7 is a fragmentary View in elevation illustrating the normalposition of the ole vice for preventing the wind wheel from being forcedout of operation by a blast of air, an abnormal position of itscontrolling mechanism being illustrated at the left of Fig. 1;

Fig. 8 is a view similar to Fig. 7 showing another p os1tion'of parts;and Flg. 9 1s a fragmentary perspective view illustrating the manner ofconnectin'g'the' braces and stays.

My improved windmill is designed in such a manner that it may beconstructed entirely of metal, is entirely automatic in its action andis so mounted as to obviatethe necessity for a regulating vane, the millbeing so mounted relative to its pivot thatit will at all times swing tosuch a point that it will face the wind. The mill'is also provided witha governor so connected with the vanes that they will be turned at anangle tothe wind corresponding with its speed. and eX- tremely highwinds will turn the flat blades or vanes so that they present lesssurface to the wind.

The mill is supported upon a cast metal frame A, the latter having arotary bearing or pivot 1 mounted upon the upper end of 5 standards 2and adapted to turn freely accordance with the direction of thewind. Ahorizontal bearing sleeve 3- is'provided integral the frame A andprovides mounting for a horizontal shaft 4. A drive pinion 5 islixed toone end of the shaft 4 and meshes with a gear wheel 6, the lattermounted upon I p a shaft 7 supportedin a bearing 8 above the sleeve 3, Acrank pin'9 is provided'on the gear wheel 6 and is connected by a link10 through the frame A desired point.

p with the plunger rod 11, the latter projecting and extending to any" 7vided with a series of radial spokes 13, the

latter supporting at their outer ends blades or vanes 14 which arepreferably of sheet metal and theouter ends of said s'pokes'aresupported and strengthened by means of guys 15" and 17 connected atopposite sides of the spokes, the guys 15 extending to and secured toafldisk 16 fixed on the bearing sleeve 3. Thefguys 17 I extend in theopposite direction and are secured to aldisk 18 which is located on theshaft andclamped between nuts 19 on the screw threaded end20 of saidshaft.

p The blades or vanes 14 are connected at or near their edges by stays24 which compel them to turn together so that their angular dispositionwill always be the same. A governor Bis provided on the shaft 4 and isautomatically control the angular disposition of the blades. prises twopairs of pivoted links which are connected to the arms 22 at theirntermediate pivotal connection. These arms at one end are connected to asliding sleeve 26 mounted on the shai't 4and engaged by a coiled spring27 on said shaft. The other ends of the arms 25 are connected to collar28 mounted on asliding sleeve 29, said sleeve adapted to slide on theouter face of the bearing sleeve 3. e

A link 30 is pivotally connected to the sleeve 29 and projects throughthe disk 16 and is guided in its longitudinal movement by parallel webs31 on one side ot the bearing sleeve 3. A rod 32 connects this link 30with a bell crank lever 33 mounted on an upwardly projecting arm 34 offrame A. An arm 35 is pivotally connected to one end of: the bell cranklever 33 as shown at 36, and a coiled spring 37 connectsv the upper endof thearm 35 with the other member of the bell crank lever 33 normallyholding said lever against a shoulder 38; on the lever. A lug 39projects from the arm 35 adjacent its pivot 36 and an operating rod 40is connected tothe lug 39. The arm 35 may be made with an adjusting bolt41 at its lower end to vary the length of the arm for a purpose whichwill hereinafter appear. v

Fig. 7 illustrates the normal position of the arm 35. Fig. 8 shows theposition of the arm when a sudden gust'of wind strikes the blades orvanes and operates the governor which wouldtend to straighten the bladesand prevent. any turning movement of the wind wheel unless such movement7 were limited, and it will be noted that'in Fig. 8, the'lower end ofthearm 35 engages,

the frame A and limits the further move ment of the parts. I

When it is desired to throw the wind wheel entirelyout of operation, apull is operation. When the rod 40 is released,.the. parts. will returnto normal position, thespring 37 drawing the arm 35 against the shoulder38, as illustrated in Fig. 7.

Pairs of double or parallel guy rods 41. are provided between certainblades or vanes- 14 and are connected at their inner ends to the disk 18and at their outer ends to the stays 21. These rods 41 arev connected atsuitable intervals by couplings 42 and be.- tween the outer pair ofcouplings the rods are slightly curved and support slightly The governorB com curved strips 43 between which the governor arms 22 project andare guided in their movement by said curved strips preventing lateraldisplacement, or, in other words, supporting the arms against thetendency to bendlaterally. The strips 43 are made with perforated lugs44 at-their ends receiving the rods 41 and are held against longitudinalmovement by the couplings 42. The outer ends of the. governor arms 22are connected by links 45 with the blades or vanes,

and said blades or vanes are made with eyes or loops 46 for; theattachment of the links above described. These links 15113LVOO11twardlyprojecting hooked ends 49- which facilitate the assembling of parts andform a firm connection between the governor arms and the blades orvanes.

In Fig. 3 1 illustrate a longitudinal scction and in Figs. 4, 5 and '61illustrate CI'OSS-SGGtlOl'lZtl views of the blades or vanes,

from which it. will be noted that the outer ends. of the blades or vanesare provided with stifiening ribs 50 and plates 51 to:

eye 21 for attachment to the spoke 13which serves the purpose ofconnecting both the guy and thestay.

As above indicated, this invention is de signed asv an improvement uponthe structure illustrated in. my prior Patent Number 626,559, and theoperation or the parts in general is the same, the improvements of thisapplication beingspecific to certain features and in the descriptionabove I have laid emphasis upon such features onl-vas appear to benovel.

Theinvention, of course, is not limited to the precise details ofconstruction, but to improved features which cooperate in the productionof the: windmill which is an improvement as a whole in the art.

One of the most essential features of my invention is. the automaticcontrol which prevents the wind wheel from being thrown entirely out ofoperation by a sudden gust of wind. This mechanism is illustrated bestin Figs. 1,, 7 and 8, Fig. 7 showing, the nor mal position of parts. Asabove explained, when a sudden gust of wind operates the governor, thearm 35 will engage the frame e A and prevent. further movement of theblades or vanes, thus holding them at a slight incline to compelthe windwheel to turn, and after'the sudden gustof wind haspassed, the. partswill return. to their former positions and operate. asbefore. Byadjusting thev length 0. fthe; arm 35., through the medium of the bolt.41 at the free end thereof, the exact movement caused by a gust of windcan be regulated and the mill can be thrown entirely out of operation atany time desired by a pull on the rod 40, as above explained.

Various slight changes may be" made in the general form and arrangementof parts described without departing from the invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claims.

I claim:
